Title: RE: Pass word recovery again
Ooops - sorry - I just checked - it was the other way round - when my
pc was in the console port of the access router it worked ok.
Same as the lab so it'll work on the day.

This was an issue that arose in the group a while ago.
I telnet to my access router and reverse telnet to the rest of the
lab. Password recovery on all routers in the lab works fine in
this case. They're all different 2600 flavors, bar a 2514, and the
access router is a 2509.
If I remember correctly, problems occured if your pc was using the
console port on the access router - there were however, a variety
of fixes that people sent in for different o/s flavors. I know you
checked the archive but it should be there - I'd be inclined to
check again.

This may not be what you are trying to do but I have done this with
a
Unix machine. So telnet to the router's console port through a
commserver
with the port number. ie. telnet <commserver ip address> <vty port
#>.
Then see if you get a response back from the router. Now power off
router.
Wait a few seconds and then type ctrl ]
Will respond with telnet>
type send brk
This will send a telnet break to the commserver that will be sent
to the
router console port. And the router will go into rom mode.
Then do the normal password recovery.
